In vitro activity of BMY 28100, a new oral cephalosporin

BMY 28100, a new oral cephalosporin, demonstrated good in vitro activity against common gram-positive and gram-negative respiratory and urinary tract pathogens. Its activity was shown by microdilution techniques to be generally higher than those of ampicillin, cephalothin and cephalexin, but comparable to those of cefaclor and, except for Haemophilus spp. and Branhamella spp., to amoxicillin/clavulanate.
